错误：没有名为"register.forms"的模块，使用脆皮表单 django

Question

我正在尝试以脆皮形式安装django用户注册模块，但出现错误：

No module named 'register.forms'

给我问题的确切行似乎是

from .forms import RegisterForm

我确实安装了脆皮表格

(secret) user@client:~/www/src/exchange $ pip3 install django-crispy-forms
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: django-crispy-forms in /home/kermit/Env/secret/lib/python3.7/site-packages (1.9.0)

.

(secret) user@client:~/www/src/exchange $ cat register/views.py              
from django.shortcuts import render, redirect
#from django.contrib.auth import login, authenticate
from django.contrib.auth.forms import UserCreationForm
from .forms import RegisterForm
# Create your views here.
def register(response):
if response.method == "POST":
form = RegisterForm(response.POST)
if form.is_valid():
form.save()
return redirect("home/")
else:
form = RegisterForm()
form = UserCreationForm()
return render(response, "register/register.html",{"form":form})

(secret) user@client:~/www/src/exchange $ cat register/form.py
from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from django.contrib.auth import login, authenticate

class RegisterForm(UserCreationForm):
email = models.EmailField()
class Meta:
model = User
fields = ["username", "email", "password1", "password2"]

如何加载模块"表单"？

Answer 1

问题在您的register/views.py中，第 4 行。您正在尝试从.forms导入，这是当前应用程序的forms.py。您不能有名为register/forms.py的文件。

更改从from .form import RegisterForm导入或将register/form.py的文件名更改为register/forms.py。后者是公约推荐的解决方案。
